PROBLEM TO BE SOLVED: To provide a sample chamber used for gas adsorption tests. SOLUTION: The gas adsorption sample chamber includes a plurality of thin film substrates and fluidly connects the substrates to a Sievert apparatus or other gas adsorption analyzer. The thin film substrates are disposed in a column and held near each other in overlapping arrangement or arrangement with small gaps so that the accuracy of the adsorption test is improved by reducing the free gas volume in the sample chamber. The internal structure of the chamber is composed so that the clearance between the thin film substrate and the internal surface of the chamber is the smallest, and thereby almost all of the space in the chamber is occupied with the thin film sample material and inert substrate material. To facilitate the use in the glove box, the chamber may includes a retrievable sample cartridge in which a plurality of thin film substrates are disposed so that all substrates are put in or taken out all together.
